Abstract

FIELD: underwater shipbuilding.

SUBSTANCE: invention relates to underwater shipbuilding, and in particular to rescue underwater vehicles designed to rescue the crews of emergency submarines and underwater objects. The rescue underwater vehicle contains a landing and suction chamber, a compartment for the rescued, a control compartment and a power plant. The vertical cylinder fixed to the body of the apparatus is open at the top and bottom, into which the compartment for the rescued is inserted and secured with quick-release connections. Compartment for survivors is made in the form of a vertical cylinder and is divided by a horizontal bulkhead into an upper part for accommodation of rescued and decompression and a lower part, open from below, which is a landing and suction chamber.

EFFECT: speeding up the time of the rescue operation and eliminating the need to interrupt the decompression process.

Description

The invention relates to underwater shipbuilding, in particular to rescue underwater vehicles designed to rescue the crews of emergency submarines and other inhabited and underwater objects, having special docking stations for docking with underwater vehicles.

Known rescue underwater vehicle according to the patent of the Russian Federation 2615029, including a housing, landing chamber and suction in the lower part of the housing. Known similar technical solutions used on foreign rescue underwater vehicles ("Rescue underwater vehicles", "Shipbuilding abroad", ed. Central Research Institute Rumb, No. 3, 1987, pp. 5-15).

Known rescue underwater vehicle according to the patent of the Russian Federation No. 2334650, IPC B63G 8/00, B63G 8/40, including a body with equipment and systems, a propulsion and steering system, a landing and suction chamber located in the lower part of the body. When carrying out a rescue operation, the device according to the patent of the Russian Federation No. 2334650 MPK B63G 8/00, B63G 8/40 lands on an emergency object, while the landing and suction chamber is installed on the emergency coaming platform, after which water is pumped out of the landing and suction chamber, due to which the rescue underwater vehicle is fixed on the emergency object, and it becomes possible for the crew to move from the emergency object to the compartment of the rescue underwater vehicle. After that, the hatches on the emergency facility and the rescue submersible are closed, the landing and suction chamber is filled with outboard water, the rescue submersible is separated from the emergency facility and delivers the crew of the emergency facility to the rescue vessel. If necessary, if the number of seafarers to be rescued exceeds the possibility of their simultaneous transportation by a rescue vehicle, the operation is repeated.

Known rescue underwater vehicle containing a control compartment to accommodate the crew and a compartment to accommodate rescued. It is equipped with a transitional hatch with a transitional shaft (landing and suction chamber for SPA on an emergency object).

A rescue underwater vehicle is known according to the patent of the Russian Federation No. 2761043, 2021, IPC B63G 8/00, characterized in that it contains a compartment for rescued in the form of a vertical cylinder installed near the center of gravity of the rescue vehicle, divided by a horizontal bulkhead into two parts. The lower part is a landing and suction chamber, and the upper part is a compartment for the rescued. If necessary, rescued persons can be decompressed in the rescue compartment. The well-known technical solution according to the patent of the Russian Federation No. 2761043, 2021 is taken as a prototype.

The disadvantage of the known technical solution adopted for the prototype is the following. The time of decompression depends on the depth of immersion of the emergency object and the time spent by the rescued at elevated pressure. For example, according to the publication “Handbook of a diver” (under the general editorship of E.P. Shikanov, M., Military Publishing House of the USSR Ministry of Defense, 1973, tables 15.1-15.10), after staying at a depth of 75 m for an hour, the decompression time can reach 5-8 hours, and with an increase in the time spent under increased pressure, rescued can reach a greater value. Thus, when conducting decompression directly in the compartment for the rescued, in order to speed up the rescue operation, it is necessary either to interrupt the decompression to transfer the rescued to the decompression chamber on board the rescue vessel and perform a repeated rescue cycle using the rescue apparatus, or to wait for the end of decompression, as a result of which the rescue operations are slowing down.

The purpose of the proposed technical solution is to eliminate this drawback, namely, to speed up the time of the rescue operation and eliminate the need to interrupt the decompression process.

This goal is achieved by the fact that, unlike the prototype, the rescue underwater vehicle contains a vertical cylinder fixed to the body of the apparatus, open at the top and bottom, into which a compartment for the rescued, made in the form of a vertical cylinder, is inserted and fixed with quick-release connections, divided by a horizontal bulkhead into the upper part for placement of rescued and decompression and the lower part, open from below, which is the landing and suction chamber.

The proposed technical solution is illustrated by the drawing, where in Fig. 1 shows a rescue submersible.

Rescue underwater vehicle contains a housing 1, which houses the control posts and power plant. A vertical cylinder 2 is fixed to the body 1, open at the top and bottom. In cylinder 2, a compartment for survivors 3, made in the form of a vertical cylinder, is placed and fixed by quick-release connections, divided by a horizontal bulkhead into a compartment for accommodation and decompression of rescued 4 and a landing and suction chamber 5.

At least one eye 6 is attached to the upper part of the rescued compartment for quick extraction of the rescued compartment and its installation after the rescue apparatus has surfaced on the deck of the rescue ship.

When carrying out a rescue operation, the rescue underwater vehicle with the compartment for the rescued 3 installed in the vertical cylinder 2 lands on the emergency object, the landing and suction chamber 5 is installed on the coaming platform of the emergency object. Rescued people move into compartment 4 and close hatch 7 behind them. After that, the rescue underwater vehicle separates from the emergency object and begins to ascend to the surface. At the same time, if necessary, decompression of the survivors in the compartment 4 begins. After ascent, with the help of eyelets 6, the compartment for the rescued is removed from the rescue underwater vehicle and installed on the rescue vessel. In this case, the decompression mode continues. Another compartment for the rescued 3 is installed and fixed on the rescue underwater vehicle, after which the dive to the emergency object is carried out.

Thus, the proposed technical solution, characterized in that the rescue underwater vehicle contains a vertical cylinder fixed to the body of the apparatus, open at the top and bottom, into which a compartment for rescued, made in the form of a vertical cylinder, is inserted and fixed with quick-release joints, divided by a horizontal bulkhead into an upper part for placement of the rescued and decompression and the lower part, open from below, which is the landing and suction chamber, allows you to achieve the goal, namely, to ensure the acceleration of the rescue operation and the elimination of the need to interrupt the decompression process of the rescued.
